Jsi is a C (+/-) embeddable JavaScript interpreter (like Python, Lua, Tcl, etc) that:

• can use typed functions,
• has builtin support for web and database,
• is easier to learn because the syntax is javascript.

A Jsi function may have parameters with types and default values, eg:

function foo (n:number, str:string=''):number { return n+str.length; }

Types are also used in the generation of C extensions.
